CHANNEL-FLAP TURNER.

SPECIFICATION forming part of Letters Patent No. 588,970, dated August 31, 1897.

Application filed October 9, 1896.

Be it known that 1,.WILLIAM E. FISCHER, of Boston, county of Suffolk, State of Massachusetts, have invented an Improvement in Channel-Flap Turners, of which the followin g description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object the production of a novel machine for turning over the flaps of channels cut in leather soles, my present improvements adding greatly to the efficiency of the machine.

I have devised a novel feeding mechanism, the same presenting two wheels working side by side, the shaft carrying and actuating said wheels being so supported that the center of rotation of one of said wheels maybe readily varied with relation to the center of rotation of the other of said Wheels, such'jchange of center enabling one of said wheels to engage the inner face of the sole near its edge to feed the sole, While the other of said wheels supporting the sole near its median line may yield somewhat as the wiper to be described acts on and lays the channel-flap over, such yielding of the said wheel obviating putting so much strain on the flap as to tear the same. These Wheels may be adjusted vertically as to their position, and their relative levels may also be varied by adjusting devices.

In this my improved machine the shaft carrying the wiper revolves in a yoke adapted to turn about a vertical pivot erected on a horizontally-sliding frame, such construction enabling the said wiper to be adjusted toward and from the feed-wheels to accommodate the machine to the particular diameter of the wiper used or to enable the said Wiper to be adjusted so as to occupy a position entirely beyond the feed-wheels, so that the operator, holding a lasted shoe in his hand, it having laid on it a channeled outer sole, may have the flap of the said channel turned or on, but firmly fixed to, the inner sole.

By moving the yoke having the bearings for the wiper-shaft aside about the vertical pivot the wiper may be readily changed and one of the desired diameter or thickness put in place, and then the said yoke may be moved back again into the desired position over the Serial No. 608,410. on model.)

foot or presser, which bears on the sole in opposition to the feed-wheels, the free end of said foot also entering the channel and serving as a guide.

I have made the flap-holder adjustable to adapt it to the diameter of the wiper used, and I have also made provision for adjusting the normalpositionof the wiper according to its diameter. The footor-presser referred to has also been made adjustable to adapt it to the diameter of the wiper. I have also mounted the idlers on a movable yoke, so that they may be readily adjusted to enable the actuating-belt to be driven from a pulley below the bench on which the machine sits or from shafting above thebench.

The shafts carrying the feed-wheels are located one inside the other and are supported in a pivoted frame.

The yoke carrying the bearings for the wiper-shaft is made vertically adj ustable with relation to the foot or presser.

Figure 1, in front elevation, represents a channel-flap-turning machine embodying my present improvements; Fig. 2, a right-hand side elevation thereof, partially broken out, the parts being in position to wipe back a flap of a channel made in a sole which will rest on the feeding-wheels. Fig. 3 is an enlarged section on the line 00, Fig. 2. Fig. 4 is a detail showing the manner of connecting the two shafts carrying the feed-wheels. Fig. 5 is a detail showing the manner of adjusting the position of the yoke carrying the wiper-shaft; Fig; 6 shows the hub I) detached. Fig. 7 is a section of one of the parts of the feed-wheel 19 Fig. 8, a top view of the wiper and part of the spindle to which it is attached. Fig. 9 shows the flap-presserin plan view with its shankin section. Fig. 10 is a sectional detail to be referred to, and Fig. 11 a rear view of the yoke C.

The base or frame A, of suitable shape to support the working parts, has a projection to, which enters a groove 0. in an upper frame A, a screw 0. entering a screw -threaded opening in the rib a of the base A and extending through a slot a in the bottom of the upper frame, permitting the upper frame to be adjusted longitudinally upon the lower frame and to take with it the parts carried thereby to be described.

lOO

The base has a suitable stud upon which is mounted the driving-wheel B, the hub of which is provided with a pinion B", said pinion engaging a toothed wheel B fixed. upon the right-hand end of a hollow shaft B having its bearings in a frame B pivoted at B the center of said pivot being coincident with the pitch-line of the gears B and B so that said frame may rise and fall at its outer or left-hand end.

The shaft B is a hollow shaft, and it has attached to its outer end by a suitable setscrew, as I), (see Fig. 2,) ahub 1), (shown detached in Fig. 6,) said hub having a projecting flange and being provided with a series of adjusting and holding screws b The feed-wheel next to this hub and held by the set-screw is made in sections, as best shown in Fig. 3, where the said sections are designated by the letters If, the inner side of said feed-wheels next to said hub having grooves b, in which enter the points of the screws b the said grooves and the points of the screws being so shaped that when the parts of said wheels are put into position to be confined in the machine said screws are turned in to confine the sections of the wheel in place, act against one wall of said groove to force the said wheel-section against the flange b of the hub, and at the same time they move the sections of the wheel toward each other in order that they may be locked firmly against the outside of the neck b of the hub.

Fig. 7 shows a section of one of the parts of the wheel b and with the point of a setscrew entering the groove b.

The feed-wheel c has its hub attached by a suitable set-screw c to a shaft 0 threaded at its outer end, as represented in Fig. 10, the end of the shaft being mounted in a bearing 0 made as a square block sustained in a slotted link by a spring 0 said spring being adjustable by a nut c on a rod 0 also sustained in the slot of said link, the lower end of the link being pin-jointed at c to a lever c, pivoted at c on the vibrating frame 13, the said lever 0 having attached to it a rod 0 which in practice will be connected with a suitable treadle at the fioor, so that by pressure upon the said treadle the lever may be turned to raise the outer end of the shaft 0 and consequently the wheel 0, and place its periphery above the periphery of the wheel b and in this position of the parts the wheel 0 alone becomes the feedingwheel and it alone supports the work.

For turning the flap on Goodyear inner soles I may change the position of the nut 0 011 the screw 0, so that said nut will act upon the arm 0, extending from the lever c and hold the feed-wheel c elevated above the feedwheel I), and then I adjust the frame A to the left to put the foot e in position to hold the work on the feed-wheel. The nut 0 limits the movement of the lever c when actuated by the foot of the operator. The spring 0 holds the feed-wheel 0 up with a yielding pressure, so that it may move vertically to a limited extent with relation to and across the face of the feed-wheel U". The frame 13 is free to yield up or down as it rests upon the spring (1, made adjustable in usual manner, the said spring keeping the frame and the two feed-wheels in their operative positions. The shaft 0 is extended through the hollow shaft B and rotates coineidently with it; but in order to enable the wheel 0 to move vertically with relation to the wheel I) the conneetion between the two shafts may be a sort of universal connection. I have shown this universal connection in this instance of my invention as a tri-armed spring d, attached by screws (1 to the gear E the said shaft being extended through a hole in the center of the said spring and having applied to it suitable adjusting-nuts d and 01 (See Fig. 4.) Instead of this three-armed spring I might readily use any usual form of gimbal-joint.

I have added to the base A a wedge-block 0, (shown in Fig. 2 partially by dotted lines,) and have made the same adjustable by or through a suitable screw c, the adjustment of said wedge limiting the upward position of the frame or lever B and the plane in which the feed-Wheel may normally stand, and to lock the feed-wheel and frame down in inoperative position I may depress the inner end of the frame and insert in ahole 0 a suitable pin, it crossing the bearing in which the shaft B rotates, this being done when the upper frame a is pushed far enough to the left to place the wiper to be described entirely beyond the feed-wheels, so that the operator can hold the outer sole applied to a lasted shoe up against the under side of the foot 6 said foot being also in the channel.

The upper frame has a standard 0, to which is attached a yoke O by a suitable screw 0*, (shown in Fig. 1],) said yokehaving atits ends diagonally-placed studs C upon each of which is hung an arm C havinga suitable stud C, upon which is mounted one of the idlerwheels 0.

The upper frame A has erected upon it a vertical pivot or stud D, upon which is fitted to turn the hub of a yoke D, having suitable bearings for the wiper-shaft D provided with a wiper f, having suitable lips f and shown in plan view in Fig. 8, the said wiper being threaded at its center to be screwed onto a thread at the lower end of said shaft.

The shaft has attached to it by suitable screws f a sleeve-whirl, the large part of the sleeve-whirl D having a belt-receivin g groove f it surrounding but not touching the upper bearingf for sustaining the said shaft, and consequently the upper bearing is not at all strained by the belt-pull.

In Fig. 2 the belt or band is supposed to be driven from a pulley below the bench on which the machine sets, but should it be desirable to drive the said spindle from apulley above the bench in such case the screw C will be withdrawn and the yoke C will be ICC turned over one-half way, leaving the arms 0 standing above their pivots 0 such reversal of the yoke maintaining the proper pivotal relation of the arms C so that the strain of the belt on the pulleys will be in linewith the pivots C the acting face of the elevated idlepulley a coming in line with the center of the grooved pulley f 3 of the whirl.

The hub of the yoke D rests on a spring D ,and the upper end of the stud D receives a screw D the inward turningof the screw depressing the yoke against the spring and the outward turning of the screw permitting the spring to raise the yoke, and when the yoke is in its proper position vertically it will be locked in said position by a set-screw D acting against the stud D. The upper end .of this stud (see Fig. 5) is slabbed off for part of its diameter, as at g, and a screw 9 in the hub of the yoke may be turned in the said yoke more or less in order to cooperate with the said slabbed part and limit the axial motion of thehub of the yoke D on the stud when the yoke is turned to put the wipershaft in operative position, this position being changed to accommodate the diameter of the wiper to be used.

The wipers are changed from time to time, according to the particular shape or size of the channel in the sole and thickness of flap, and to effect this change readily the set-screw D may be loosened and the yoke D may be turned about the vertical stud D, after which the wiper may be readily turned off and one of the proper size or diameter and thickness applied.

The wiper acts substantially as the wiper described in my Patent No. 128,610, dated July 2, 1872, and cooperating with said wiper isafiap-holderh, (shown separately in Fig. 9,)

- its under side being shaped to act upon and hold in its turned-over position the flap as the latter is opened over to uncover the channel. This flap-holder is adjustably attached by a screw h to ahorizontally-adj ustable block 71 in turn attached to the yoke by an ad justing-screw its, so that the said flap-holdermay be adjusted horizontally, as well as vertically, to adapt it to cooperate with a wiper of any desired diameter and also to adapt it to the varying thicknesses of the wiper.

The foot 6 is made adjustable on the upper frame A horizontally, as shown bya suitable set-screw h.

In applying the feed-wheel c to its shaft its hub is acted upon by the inner end of the bearing 0 a washer m placed against the outer side of said bearing and acted upon by a nutm, forcing the bearing against the hub of the feed-wheel and forcing the face of the feed; wheel substantially against a small collar m (see Fig. 11,) and-thereafter the set-screw c is screwed in to fasten the wheel upon the shaft.

The feed-wheels heroin shown and described Making the inner feed-wheel b in section ent ables it to be readily removed from the driving-shaft after the teeth may have become dull by wear, and another wheel-section, preferably made of steel, may be inserted instead of it, thus obviating sharpening the teeth, as heretofore done.

When wiping the flap back about the toe' of the sole, the operator will by his foot lift temporarily the feed-wheel 0, thus lessening the pressure of the sole on the feed-wheel 6 which has the longer teeth, so that the sole may be turned in a small curve and the teeth of the wheel 19 will not injuriously mar its surface.

The screw O forming the pivot for the yoke O, occupies a position in the horizontal plane with the straight horizontal run of the belt f Viewing Fig. 3, it willbe seen thatthe shaft 0 is located at one side of the center of the surrounding shaft B this being effectedby locating the bearing 0 for the outer end of the shaft 0 at one side of the center of rotation of the shaft B such location of said shaft 0 resulting in placing the centers of the two feed-wheels at a distance from each other, 9

which puts the acting peripheries of said wheels normally in such position with relation each to the other as to constantly present a layer surface to support the sole.

I have shown pointed set-screws as a means for attaching the feed-wheel sections to said hub, but the invention is not limited to just the means shown for attaching the feed-wheel sections in position, and I believe that I am the first to use a feed-wheel in section and hold it in place by independent devices.
